How to Properly Clean and Maintain a Swiss Army Knife

The Swiss Army knife is one of the most versatile tools out there, but it can easily become dirty and dull if not cared for properly.

Keeping your knife clean and sharp not only ensures that it will last longer but also makes it more effective when you need to use it.

Here’s how to keep your Swiss Army knife in top shape.

1. Cleaning Your Knife

To start off, it’s important to make sure your Swiss Army knife is free of dirt and debris before attempting any maintenance or sharpening.

Start by wiping down the outside of your knife with a dry cloth; this will remove surface dirt as well as fingerprints and smudges. Then, take a damp cloth and wipe down the blade as well as all other components, including the handle, hinges, and springs.

Be careful not to submerge any part of your knife in the water! Once finished, open all parts of the knife and make sure they are completely dry before putting them away.

2. Sharpening Your Knife

Once you’ve cleaned the blade of your Swiss Army knife, it’s time to sharpen it. The best way to do this is with a honing rod or whetstone; this will ensure that your blade gets a nice, even edge without damaging its integrity.

To sharpen using a rod or stone, place the angle of the blade at about 20 degrees against the honing surface and draw it across from heel to tip several times on each side until both sides are evenly sharpened.

Make sure not to press too hard or you could damage the edge! If necessary, you can also use an electric sharpener for faster results; just be sure that its settings are low enough so as not to cause damage.

3. Oil Maintenance

Once you’ve finished cleaning and sharpening your Swiss Army knife, take some gun oil or mineral oil (available at most hardware stores) and apply a thin layer along all metal surfaces – including blades and hinges – after wiping them down with a dry cloth first.

This will help lubricate all moving parts while preventing rust from forming on exposed metal surfaces over time. Oil should always be applied sparingly; too much can cause buildup which can attract dust particles over time.


A Swiss Army Knife is an incredibly useful tool but requires regular maintenance in order for it to stay in optimal condition.

Cleaning regularly using mild detergent (or soap if necessary), drying completely before putting away, sharpening periodically with either honing rods or stones (or electric sharpeners if available), and oiling all metal components every few months should keep your knife looking great for years!

Every once in a while it’s worth taking some time out of your day for proper care of such an invaluable tool – after all, these knives aren’t cheap!

Taking care of your Swiss Army Knife now will save you money in the long run by ensuring its longevity so that you won’t have to buy another one anytime soon!
